It is. The pump and dump groups bring money to group moderators, not all participants. Participants can take advantage of signals but only people who don't sleep and receive signals very early can get profits. Later signal receivers (off line, wake up too late) will buy at higher price and if unfortunately enough they will buy at take profit price of others in the same group.

Rely on signals and they won't care why price is pumped and why do they receive signals. They are classic fomo people.
